Does anyone know how to get the year from the VIN? I was told its an '89 YZ250, but recently have had some part fitment issues and just wanted to make sure of the year. I have no docs. on the bike at all, just the VIN.

funny you mention that, the motor blew up about 3 rides after i bought it... power valve failure. I attrubuted it to assembler error though. The bolt on the powervalve linkage was loose (like 2 threads from falling out). Which allowed the power valve to rotate back too far and contact the piston and there fore destroy it and the cylinder. The bike was advertised with "brand new top end"... you know the deal.
